J. S. Toll Fellows Program - Chesapeake Bay’s ‘forgotten’ Anacostia River: Eutrophication and nutrient reduction measures
The Anacostia River, a Chesapeake Bay tributary running through Washington, D.C., is small but highly polluted with nutrients and contaminants. There is currently a multi-billion dollar tunnel project underway, being built in several phases, aimed at diverting effluent, especially during high flow periods, and improving water quality of the Anacostia and the river into which it flows, the Potomac. Data from four years of biweekly to monthly sampling including nutrient and phytoplankton data were analyzed to assess pre-tunnel eutrophication status and relationships to flow condition. The Anacostia Tunnel implementation in March 2018 and associated nutrient reductions may reduce the severity of summer blooms but may have a greater effect on spring assemblages depending on flow conditions.
Caroline Solomon is a Professor of Biology and Chair of Department of Science, Technology and Mathematics at Gallaudet University. Her ongoing research program explores nutrient dynamics and its influence on the microbial community in the Anacostia River. In addition, she is an award-winning teacher – among other honors, she was named one of National Public Radio’s “50 Great Teachers” in 2015 – and a nationally-recognized advocate for deaf and hard of hearing people in the Sciences.
